I have what appears to be an insect bite on my right shin. I ve had it for about a week, and the redness started to increase about 3 days ago. I ve washed it with cold water and soap, to avoid the added irritant of warm water, and have applied aloe vera gel to it to try to decrease and get rid of the irritation, itching, and redness. This method has not worked: the red area has only expanded, and, for about the past day, there has been a slight, dull soreness that goes from the bite center around my leg to the back side of the leg.
